Multi-Bandpass Optical Filters

The commercial availability of Light-Emitting Diodes at almost any wavelength combined with Multi-Bandpass Filters have enabled a completely new type of instrumentation. These instruments allow ultrafast switching between different wavelengths without the need for moving or replaceable filters parts. An example of an application is fast time-gated fluorescence microscopy. A Multi-Bandpass Filter is an optical filter capable of transmitting two or more distinct wavelength bands while blocking others. The filters should exhibit high passband transmission, deep out-of-band blocking as well as steep edges. Furthermore, the filters should often be tailor-made for a specific instrument and application.

Delta Optical Thin Film A/S has many years of experience with OEM manufacturing of high-performing Multi-Bandpass Filters tailored to their customer’s specific requirements. Using advanced magnetron sputtering combined with decades of experience in filter design and manufacturing, Delta Optical Thin Film A/S can help customers identify the right filter solution for their application. The unique combination of large batch sizes and short production time at Delta Optical Thin Film A/S allows these advanced optical filters to be manufactured in volume at very competitive prices.More products
